They can't seem to figure out what it does beyond emitting teraherz waves.
I wonder if it's a neutron trap?
I was involved in that.
Someone sent Art Bell some evidence of UFO material related to the 1947 Roswell crash. The whole episode was called ‘Art’s Parts’.
I predicted at the time that it would be material available in 1947 and furthermore, that it would be sintered. Sure enough, it was sintered.
Even today, sintered boundary layer control technology is STILL classified.
